O
- OFDM (orthogonal frequency division multiplexing)
- A process that divides a modulated signal into multiple sub-carriers prior to transmission through the air medium in order to improve performance. 802.11a and 802.11g wireless LANs and some proprietary wireless MANs utilize OFDM.
- optical fiber
- A long piece of glass having a very small diameter covering that is able to carry light signals from one end to the other. An optical fiber cable has a protective coating, making it difficult to distinguish from copper-based cables.
